The outer conductor of this cable is constituted
of a corrugated tube (spiral winding).
This construction allows perfect shielding and
bendability while respecting large bending
radius.
The foam dielectric provides excellent loss and
low return loss levels.
This cable will be advised for feeder and
jumper assemblies in cellular networks as well
as applications requiring high performance
level on long distances.
The anti-UV LSZH (Low Smoke Zero Hallogen)
material is also flame retardant and allows
this cable to be used for indoor public areas
as well as outoor installations.
